GSM-gateways Polygator allow to setup special mode of interaction between the GSM-gateways and Base Transceiver Station (BTS). For example, there is special mode for switching automatically between visible 6 base stations on certain conditions.

Switching among BTS is performed during pauses between voice calls. Frequency of BTS switching is set by randomized time bounds. Besides, some of visible base stations can be excluded from the list. The list is available on the web-interface of GSM-gateway and accompanied with some additional information. Operation mode and base stations list can be set up for each GSM-module individually.
